Application inea April 15, 191e. serial no. 91,423.

To all io hom it may concern. Y

Be it known that I, FRANK' DvoRAK, a citizen of the United States,residing at Dickinson, in the county of Stark 'and State of NorthDakota, have invented certain new and useful Improvements in Magazine-Hammers, of which the following is a specification.

This 'invention relates to an improved magazine hammer and the principalobject of the invention is to provide a hammer having an improved typeof nail holding compartment or chamber adjustably mount-ed and tofurther provide improved means for feeding nails out of the compartment.

Another object of the invention is to provide improved means foradjusting the position of thenail holding compartment and to alsoprovide improved means for actuating the revolving cylinder for feedingthe nails out of the compartment, the actuating means for the cylinderbeing connected with an abutment bar so that the abutment bar will movein timed relation to the cylinder. Another. object of the invention isto so construct the mechanism for actuating the abutment bar andcylinder that it will be `yieldably held in a normal position.

This invention is illustrated in the accompanying drawings whereinFigure 1 is a view showing the magazine hammer in side elevation. Fig. 2is a view showing the hammer iii longitudinal section. Fig. 3 is a viewshowing the hammer in top plan. Fig. 4 is a fragmentary sectional viewshowing the manner of mounting the lfeeding cylinder. Fig. 5 is avertical sectional view through tlie frame in which the tube carryingthe cylinder is mounted. Fig. 6 is a view in side elevation of the tubeand cylinder. Fig. 7 is an end elevation of the nail receptacle. Fig. 8is a perspective view of the latch plate for releasably holding 'theadjusting strip in a set position. Fig. 9 is a perspective view of theadjusting strip for the nail holder.v Fig. 10 is a perspective view ofthe rocker arm connected with the trigger of the hammer. Fig. 11 is aperspective view of a device for vtemporarily holding the nails in thepassageway formed in the head of the hammer. Fig. 12 is a fragmentarysectional view showing the tack holder of Fig. 11 mounted in the hammerhead. Y

This hammer is provided with a handle 10 and head 11 above'which thereis located a i housing 12. This housing 12 is provided at its forwardend with an extracting head 13 which is located abovel the driving head11, and has its forward end formed into hinge ears 14 between which arepivotally mounted, the hinge ears 15 of the supporting plate 16 so thatwhen the pin 17 is in place, the supporting plate will be movablymounted and may be swung outwardly.

Within the housing 12 which is provided with a sliding closure 18, thereis positioned a nail supporting rack or frame 19 formed from U-shapedstrips connected as shown in Fig. 7 to provide arms 20, 21 and 22. Theupper ends of these arms are flared thus providing means for supportingnails between the arms 20 and between the arms 21 .and 22. Tongues 24and 25 extend rearwardly from the nail supporting frame as shown in Fig.2 with the tongue 24 resting upon the tongue or lip 26 and a securingpin or bolt 27 is passed through the tongues 24, and 26 to releasablyand pivotally mount the frame. An adjusting strip 28 extends beneath theframe between the abutment tongues 29 and is provided with an opening 30through which the pin 27 passes to pivotally mount this adjusting stripthus permitting the nail frame to be shifted to the proper position inthe housing 12 when desired. An actuating handle 31 extends upwardlyfrom the outer end of this adjusting strip to facilitate swingingmovement of the strip and from the opposite side of the outer end ofthis strip there extends a tooth 32 which will Afit into a selected oneof the notches 33 formed in the overhanging flange 34 of the latchplatey35. After the nail holding frame has been moved td the desiredposition with the outer end portion of the adjusting strip compressed topermit swinging of the strip, the strip will be released and theY spring36 will return it to the normal position thus moving the tooth 32 intoone off the notches 33 of the flange 34.

A frame or'supporting bracket 37 is secured to the plate 16 by means ofrivets 38 and carries a casing 39, one portion of which forms av tube 40for permittingk nails to pass ldown into the passageway 41 of thedriving head 11. `A feeding 'cylinder 42 is rotatably mounted in thecasing 39 as clearly shown in Fig. 4 and is provided with a pocket 43 toreceive the nail which passes into the casing through the inlet slot 44of the supporting bracket 37.` This feeding 5 The rack bar d'7extcndsthrough the housing l2 to one side of the nail holding rack orframe 19V and is connected with the rocker arm 4S by means or the linka9. The lower end of this rocker arm i8 is connected with `the triggerrod ..50 and therefore when the trigger rod 50 is drawnV to move Vtheabutment bar l outwardly, the. rack bar will;

be moved to rotate the cylinder i2 and de- .posit a nail inthe tube i0through which 5 `it will pass into the passageway all. i spring 52 isprovided to prevent the nail from dropping out through the passage wayal' but permit .the nail to pass through this passage after it has beenstarted in the wood. Then the trigger rod 50 is released, the spring 53whicliis mounted upon pin will return the rockerarin -lS to its normalposition, thus rotatin-O' the cylinder and returning it to tliepositionshown in Fig. 2 and atY 5 the saine time moving the abutment bar 5lacrossth'e'upper end of the passage il so that when the nail strikes thework, the head of the nail will hit against this abutment bar .andpermit the nail to be driven into the 0 :Work a shortdistance. The nailcan then be drawn out through the passage way stl, and

can be driven into the work as far as desired by striking with thedriving :head 1l.

lil/Then in Vuse the nal-ils are placed in the supporting iii-ame and ifdesired three sizes `of nails can be placed in this traine, the

:trame will be moved'to'feed the proper size :nail into the pocket of.theY cylinder 42 and the trigger, will then be pulled rearwardly thusfeedinga nail into the passage il while .theabutment lia-ris moved outof' the way.

The abutment bar will :then return to the position shown in Fig. 2 whenthe cylinder returns to the normal position tor receiving Va second nailand the nail can be driven `into the work as already described.

V'Therefore the .nailsv can be easily Uted out ofthe hammer and lvarioussizes can be carried in the na-il compartment. if desired, the lspring:52 can be :done away with vand the nail helder shownin ll used. This:nail holder includes an anchoring tube 55 :having arms 56 .eX-tendingtherefrom, bowed Y outwardly to provide a passage 57 Vthrough 5 whichthe nails will pass. This device will be 'placed in the driving headwithvthe arms verdiendingk transversely vof the head and the -`pocket 57positioned in the passage 4:1. Therefore the ,nails will. pass throughthis o' pocket and will be releasably held therein by .fthespringsaction fof the arms 56.
